A more control-oriented approach was tried on this thread:
http://www.themanadrain.com/index.php?topic=35407You may want to consider the following:
1) if your #1 goal is to resolve standstill, you want reactive countermagic, not proactive disruption. Drawing Duress and Thoughtseize is terrible when StandStill is on the board.
2) you DEFINITELY want Force of Will. Perhaps I did not see it in the list but I believe its missing.
3) the deck has almost no game vs shops. The null rods will help but the mana curve is so high that Sprite turns into an overcosted 1/1 with instant abilities.
4) Bitterblossom is a nightmare if your opponent drops oath the next turn. The card is insane when it gets going, dont get me wrong, but you want to make sure you can stop your opponent from winning on one insane turn which is normally what people try to do when Standstill is on the table.
If you PM me I will send you the list we came up with, I would post it here but I have to get to work

It was developed for the meta before the b&r list and really didnt lose a whole lot when blue was restricted, but with shops and ichorid expected everywhere, it definitely lost some of its potency.
